WEATHER STRIP.

Application filed March 3, 1922. Serial No. 540,694.

To all whom it may concern.

Be it known that I, ALFRED M. LANE, a citizen of the United States, anda resident of the city of St. Louis and State of Missouri, have inventeda new and useful Improvement in Weather Strips, of which the followingis a specification.

y invention relates to weather strips.

Heretofore there has been great difficulty in weather-proofing doorsills and hinged window sills due partly to the fact that storm waternaturally accumulates to a greater or less extent on such sills and isblown through the crack beneath the door or window, and partly alsotothe fact that water-flowing down the side of the frame may be deliveredonto the sill back of the sill weather strip. The principal object ofthe present invention is to overcome this difliculty; and it consistsprincipally in correlating the side strips with the bottom strip .50that the side strips are located outwardly beyond the bottom strip; andit alsoconsists in equipping the sill with a member comprising an upperstrip that is relatively rigid and a lower strip that is resilient, andin equipping the door or sash with av strip adapted to pass between saidrigid sill strip and the resilient sill strip beneath the same.

ment lastmentioned together with Weep oles or outlets for deliverin thewater outwardly from the engaging strips; it also consists in thearrangement above described together with a wind break on the outer orexposed side of the device; it also consists in the arrangements andcombinations of parts hereinafter described and claimed. 1

and

Figs. 6, 7, -8, 9 and 1 0 are views similar I go Fig. 3, showing sillmembers of modified orm.

Referring to the construction illustrated in Figs. 1 to 3, the sillmember comprises a relatively rigid strip 11 and a relatively flexiblestrip 12. The rigid strip is oflset to form a 2 section and the outermargin or flange thereof is fastened to the sill A while the innermargin is raised above the sill and the middle web portion that connectsthe two flanges is vertically disposed and providedwith weep holes oroutlets 11 near the lower flange. The resilient strip 12 has a flathorizontal portion that rests on the sill underneath the outer flange ofthe rigid strip, while the inner portion of said flexible strip iscurled upwardly and backwardly on itself underneath the inner flange ofthe rigid strip so. as to form-a resilient hollow bead adapted foryieldable engagement with the under surface of said inner flangewhen'the sash is in the open position.

Cooperating with the sill member is the sash member, which is made inthe form of a relatively flexible flat strip 13, whose body portionslopes upwardly on each side of its middle to form a line contact withthe rigid sill member and whose inner margin is re- 7 bent on theunderside to form a looprror undercut {groove or pocket 13'. The outerthis sash strip is stifl'ene'd by a sharp rebend and is secured to thebottom of the casement'sash or door B at such height that the swingingof the sash will cause the edge of'the rigid sill stri 11 to enter saidloop. The free edge of t e loop .enter between the irmer flange of therigid sill strip 11 and the resilient hollow bead 12 of the flexiblesill strip 12, said bead yielding sufliciently to accommodate the entryof the sash strip while holding the free edge thereof in contact withthe inner flan e of saidrigid strip. In this construction, the sillstrips 11 and 12 are applied to the sill directly and withliveredoutside of the sill joint.

out any alteration of the sill; but as the sill strip projects above thesill, the outer bottom portion of the sash B is rabbeted in order thatthe loop of the sash strip 13 secured to the bottom of the sash may belocated at the same height with the raised portion of the rigid sillstrip.

The sill joint, formed by the cooperating portions of the sash or doormember, the rigid sillstrip and the flexible sill strip, remainswaterproof under normal conditions by reason of the three lines ofcontact between said members. The walls of the pocket portion of theflexible door strip press resiliently upon both sides of the rigid sillstrip an and the free edge of the pocket of said flex ible sash or doorstrip enters between the rigid sill strip and the flexible sill stripwhereby a third line of contact is formed, namely between the lowerportion of the flexible sash or door strip and the upper portion of theflexible sill strip.

The space between the side rails of the sash B and the sides C of thewindow frame are weatherproofed by any suitable weather strip, but suchstrip should be located out wardly with relationto the sill strip; thatis, the side strip should be so located that the water drainingtherefrom should be de- In the construction illustrated in Figs. 1 and2, the side strip comprises a wide strip 14 of sheet metal whosemarginal portions are doubled and which is folded lengthwise near themiddle thereof. A fold is made in the form of a tubular bead 14 and thetwo body portions lie at a considerable inclination to each other. Inpractice, the side strip is located between the side of the window frameand the sash therein, and is nailed or otherwise secured along one outermargin of the window frame, the other margin being free and adapted tobear resiliently against the side of the casement sash, when the same isclosed. As suggested above, the vertical plane of the head 14 of theside strip 14 is located outwardly with relation to the vertical web ofthe sill strip 11, so that any water that may flow downwardly along saidside strip will be delivered into the trough formed by the hollow bead12 of the flexible sill strip 12 and flow through the outlets 11* ontothe sill outside of the weatherproofing joint therefor.

One of the great advantages of the fore- .going construction is that itis not only waterproof under normal conditions but that it remainswaterproof against hard rains and driving winds. Under such conditions,there is a tendency for water to pile up on a sill and be forced throughthe weatherproofing devices. With my construction, however, the force ofthe wind is broken by the vertical member of the sill thus form twolines of contact;

I ing flange 20 adapted to be strip, that constitutes a wind break orshield, so that the space back of said wind break is comparatively freefrom the force of the elements. Any water that may be forced in betweenthe sash strip and the rigid sill strip will be delivered into thiscomparatively, quiet space between the rigid and the resilient strips ofthe sill member, from which it will pass out throughthe weep holesprovided therefor as quickly as conditions permit. v

In the construction illustrated in Fig. 4, the space between the hingedside" of the sash and the window frame is weatherproofed by means ofcooperating bead and groove strips of substantially V-shaped section.The bead strip 15 is secured to the window frame and the groove strip issecured within a vertical rabbet formed in the outer edge of the sash inposition to straddle or embrace the rib strip in the closed position ofthe sash. These strips are located outwardly with relation to the sillstrip so that water draining therefrom is delivered outside of such sillstrip.

In the construction illustrated in Fig. 5, the invention is shownapplied to a door. In this construction the sill member comprises arigid threshold plate 16 and a flexible sill strip 17 The plate 16 isfastened to the sill and has an inwardly projecting horizontal flange 16spaced above the sill and at such height to be straddled by the loop ofthe door strip 18 in the closed position of the door. The flexible sillstrip 17 is located beneath the plate 16 and has a hollow head 17located beneath the overhanging flange 16 of the plate 16. The hollowbead 17" at the inner margin of the flexible sill strip 17 is protectedagainst crushing by means of a separate base strip 19 having a flat bodyportion located beneath the inner marginal portion of the strip 17 andhaving a rib 19 located outside of nthe beaded portion of said strip.The threshold plate 16 is provided with alined weep holes 16 so that anywater delivered to the space between the rigid and resilient strips ofthe sill member will pass out through said weep holes.

In the construction illustrated in Fig. 6, a rigid door-sill plate 20has an overhangengaged by the loop of the door strip 21. A flexible sillstrip 22 is located between the door sill plate and door sill and has anupwardly inclined beaded outer margin 22 adapted to bear against theloop of the door strip in the closed position of the door. The door sillplate 20 is rovided with suitable weep holes 20 adapte to delived waterfrom the space formed by the cooperating inner marginal portions to theouter side of the door sill.

The construction illustrated in Fig. 7 is similar to the constructionillustrated in-Fig.

6, except for a slight difference in the shape of the flexible sillstrip, theisill strip 23 shown in Fig. 7 having its inner marginalportion doubled back in the form of a loop 23 which engages the underside of the loop of the flexible door strip.

In the construction illustrated in Fig. 8, the invention is shown inconnection with "a casement window. In this construction, the rigid sillstrip is shown in the form of a channel strip 24: whose inner wall isprovided at its upper edge with an inwardly extending horizontal flange24 This flange is adapted to be embraced by the loop portion of theflexible sash strip 25 in the closed position of the sash; and thedoubled under portion of said loop is adapted to engage the hollow bead26 of a flexible sill strip 26, whose flat portion is clasped betweenthe rigid-sill strip 24 and the sill. The rigid sill strip is providedwith suitable outlets 24 for draining water from the beaded portion ofthe flexible sill strip onto the outer portion of the sill.

The arrangement shown in Fig. 9 is similar to that shown in Fig. 8,except that the channel shaped sill strip 27 of Fig. 9 differs from thesill strip of Fig. 8 by having its bottom spaced above the flat portionof the flexible strip by means of depending side flanges 27 Theseflanges areprovided with alined weep holes 27 'for draining the waterfrom the space formed by the inner side of the rigid sill strip and thebeaded portion of the flexible sill strip.

In the construction illustrated in Fig. 10, the rigid sill strip isshown inthe form of a flat plate 28 which is secured to the stool D ofthe sill. This plate overhangs the inner edge of the stool and isadapted to be engaged by the loop portion of the flexible sash strip 29in the closed position of the sash. The flexible sill strip is shown inthe form of a strip 30 of Z-shaped section fitted in the angle betweenthe sill and stool, the top flange of said strip resting on the stoolbeneath the rigid strip 28 and the bottom flange being curled upwardlyand backwardly to form a hollow bead 30 underneath the overhangingportion of the rigid sill strip 28. The stool and the vertical web ofthe flexible sill strip are provided with registering weep holes 31 forconducting water from the beaded portion of said flexible strip to theouter portion of the sill.

Among the advantages of myinvention is the facility with which it may beapplied. In all cases, the two parts forming the sill member may beapplied directly without any alteration of the sill; and the onlyalteration required to be made in the bottom rail to accommodate theresilient strip therefor is to rabbet or groove the outer bottom edgethereof. Likewise, the side strip is very easy of application; as it ismerely necessary to strip having an open tubular portion underneath andnormally yieldably engaged with said flat portion,l substantially asdescribed.

2. A structure having a sill member for weatherstrips comprising arelatively rigid strip having a marginal portion spaced above the sill,and a relatively flexible strip wardly and backwardly underneath andnormally yieldably engaged with said marginal portion of said rigidstrip.
